O men! serve your Lord Who created you and those before you so that you may guard (against evil). 21 The One Who has appointed the earth a base for you, and the sky a canopy – and caused water to pour down from the sky, thereby producing fruits as food for you; and do not knowingly set up rivals to Allah! 22 And if you be in doubt whether the Book We have sent down to Our Servant is from Us or not, then produce, at least, one Surah like this. You may call all your associates to assist you and avail yourselves of the help of any one other than Allah. If you are genuine in your doubt, do this. 23 But if you fail, as you are sure to fail, then guard yourselves against the Fire whose fuel is people and stones, prepared for the unbelievers. 24 And give glad tidings (O Muhammad) unto those who believe and do good works; that theirs are Gardens underneath which rivers flow; as often as they are regaled with food of the fruit thereof, they say: this is what was given us aforetime; and it is given to them in resemblance. There for them are pure companions; there for ever they abide. 25 ۞ God is not loath to advance the similitude of a gnat or a being more contemptible; and those who believe know whatever is from the Lord is true. But those who disbelieve say: "What does God mean by this parable?" He causes some to err this way, and some He guides; yet He turns away none but those who transgress, 26 Those who break the covenant of Allah after ratifying it, and sever that which Allah ordered to be joined, and (who) make mischief in the earth: Those are they who are the losers. 27 How will ye disbelieve in Allah whereas ye were lifeless and he quickened you; thereafter He will cause you to die, thereafter He will give you life, thereafter unto Him ye shall be returned! 28 He it is Who created for you all that there is on the Earth; He then turned to the sky and ordered it into seven heavens. And He has full knowledge of everything. 29
